Abstract
We first revisit the problem of on-off keying demodulation with fixed detection thresholds over atmospheric turbulence channels. The resulting error floors are derived for a variety of turbulence channel models. To eliminate the irreducible error floors, we propose a detection system based on the electrical signal-to-noise ratio. Such a system offers performance compromise between the optimum system with time-varying detection threshold and the suboptimal system with fixed detection threshold.
